Sebenzisa:I-1,1-timethylurea (n, n-dimethylurea) isetshenzisiwe ku-dowex-50w ion Exchange resin-inyusa ukuhlanganiswa kwe-N, N'-Discubed-ARYL-3,4-Dihydropymimidinanes.
Isingeniso Esinemininingwane
1,1-milethylureaiyingxenye yamakhemikhali ngefomula ye-molecular c3h8N2O. Yaziwa nangokuthi dimethylurea noma i-DMU. Kuyimpuphu emhlophe ye-crystalline, incibilika kalula emanzini kanye ne-organic solvents.
I-1,1-timethylurea inezicelo ezahlukahlukene ezimbonini ezahlukene. Okunye ukusetshenziswa kwayo okuyinhloko kunjenge-reagent ekuhlolweni kwe-organic. Isetshenziswa kakhulu njengomthombo we-dimethyyamine, ibhulokhi yokwakha ebalulekile ekukhiqizweni kwemithi, udayi namanye amakhemikhali.
Embonini yezemithi, kusetshenziswa i-1,1-dimethylure njengengqayizivele ye-synthersor yezidakamizwa kanye nezidakamizwa eziphakathi.
Ingasetshenziswa njenge-ejenti evikelayo yamaqembu asebenzayo abucayi ngamakhemikhali ngesikhathi sokuphendula oku-organic. Iphinde isetshenziswe njenge-catalyst ekuphendukeni okuthile.
Ngaphezu kwalokho, i-1,1-dimethylurea nayo isetshenziswa ekuhlanganiseni kwama-herbicides kanye nama-fungicides. Isebenza njenge-stabilizer futhi ithuthukisa ukusebenza kwalawa ma-agrochemical. Kubaluleke kakhulu ukuphatha i-1,1-dimethylurea ngokunakekelwa ngoba kubhekwa njengengozi uma kuthathwa noma kuthintana nesikhumba noma amehlo. Izindlela zokuphepha zokuphepha ezifanele kufanele zithathwe lapho zisebenza nale nhlanganisela, njengokugqoka imishini yokuvikela kanye nokuqinisekisa umoya omncane.
Ngamafuphi, i-1,1-dimethylurea iyindawo esebenza ngempahla esetshenziswayo engafakwa ekuhlolweni kwe-organic, ezemithi kanye nama-agrochemicals. Izakhiwo zalo zikwenza kube lusizo njenge-realent, evikela, kanye ne-talyst ezinhlokweni zamakhemikhali ezahlukahlukene.
Isicelo
I-1,1-timethylurea, eyaziwa nangokuthi i-DMEU, inezicelo ezimbalwa ezibalulekile ezimbonini ezahlukahlukene. Nazi ezinye izinto eziphawuleka:
Imboni Yezemithi:I-DMEU isetshenziswa njengengxenye ephakathi nendawo ekuhlanganiseni kwama-Pharmaceuticals. Kungasebenza njengokuphendula ekukhiqizweni kwezidakamizwa njenge-antiPyrine, i-phenobarbital, ne-theophylline. Isakhiwo esiyingqayizivele se-DMEU siyivumela ukuthi isebenze njengebhulokhi yokwakha yokwakhiwa kwama-molecule ayinkimbinkimbi ajwayelekile.
Synthesis ye-organic:I-DMEU isetshenziswa kabanzi ekuhlanganiseni kwe-organic njenge-realent noma i-solvent. Ingabamba iqhaza ekuphendukeni okuhlukahlukene kwamakhemikhali njengokuvuselelwa, i-oxidation, kanye ne-alkylation. Ukuvuselelwa kwemvume ye-DMEU nokuqina kwenza kube lula ukusabela okuhlukahlukene ukwakha amakhompiyutha abalulekile we-organic.
Imboni ye-Dyestic:I-DMEU isetshenziswa njengommeleli osebenzayo wokukhiqiza amadayi athile nemibala. Isakhiwo saso samakhemikhali siyivumela ukuthi babambe iqhaza ekuphendukeni okuholela ekwakhekeni kwemibala esebenzayo futhi eqinile. Ama-molecule edayi akhiqizwa esebenzisa i-DMEU angasetshenziswa ezimbonisweni, ama-inks wokuphrinta, nezinye izinhlelo zokusebenza ze-dyestuff.
Imboni ye-polymer:I-DMEU inezicelo ekukhiqizweni kwama-polymers nama-resin. Ingasetshenziswa njengomenzeli oxhumanisayo noma njengengxenye yokuhlanganiswa kwe-polyurethane nama-epoxy resins. Lawa ma-resins athola ukusetshenziswa kwezingubo, anamathela, kanye nezinye izimboni ezahlukahlukene.
Imboni yogesi:I-DMEU ingasetshenziswa ekwakhiweni komanyolo wokukhishwa kancane. Izakhiwo zayo ezilawulwa ezilawulwayo zivumela ukukhululwa kancane kancane kwe-nitrogen, ukuhlinzeka izitshalo ngokuhlinzekwa okuqhubekayo kwezakhi zomzimba esikhathini esengeziwe.
Kubalulekile ukuqaphela ukuthi lapho usebenza nge-DMEU noma noma iyiphi i-compact company, kufanele kulandelwe izinyathelo zokuphepha ezifanele kanye nemihlahlandlela yokuqinisekisa ukuphepha kokuphepha kwabantu kanye nemvelo.
